Ultraflex MACH Zero Heavy Duty 33C Control Cable

The Ultraflex MACHZero is a patented high-efficiency universal mechanical engine control cable for compatible throttle and shift installations. It uses an 87mm / 3.4in stroke, stainless-steel cable-end fittings and a blue outer jacket resistant to abrasion, UV and chemicals. Its flexible conduit and low-lost-motion core are intended for smooth operation in long or complex cable routes. Choose from the listed 5ft to 36ft variants.

What Is This Control Cable Used For?

The MACHZero transfers movement from a compatible mechanical control box to an engine throttle, gearbox or shift linkage.

• Compatible universal-style throttle installations
• Compatible universal-style shift installations
• Outboard, inboard and sterndrive applications using the correct accessories
• Long control-cable runs
• Installations with multiple bends or restricted routing space
• Replacement of an existing MACHZero cable with matching ends, stroke and length

The MACHZero is a premium cable format rather than a complete control system. The control box, engine linkage, cable-end hardware and cable route must all be compatible.

What Is Included?

The selected Ultraflex MACHZero cable is supplied with:

• One Ultraflex MACHZero mechanical engine control cable in the selected length
• Integral cable terminals and end fittings supplied as part of the cable assembly

Not included:

• Mechanical engine control box
• A second cable where separate throttle and shift cables are required
• Control-box connection kit unless expressly stated as part of a separate package
• Engine-side clevises, pivots, clamps or adaptors not integral to the selected cable
• Installation labour and boat-specific mounting hardware

Which Engines and Controls Are Compatible?

Ultraflex describes the MACHZero as a universal style cable like the C2 and C8. Before ordering, confirm:

• The engine or gearbox application accepts the MACHZero universal cable-end format
• The control box accepts MACHZero directly or has the specified Ultraflex connection kit
• The selected length reaches the engine or gearbox connection along the complete installed route
• The control-box end and engine end match the required terminal geometry
• The required cable stroke matches the control and engine linkage
• Any control-box or engine-side connection kit is identified before installation
• The cable can be routed without kinks, crushing, heat exposure or interference with moving components

Do not assume that every cable described generically as 33C has identical terminals, travel or connection hardware. Compare the complete cable specification before replacing another brand.

How Is MACHZero Different from C8?

MACHZero and C8 share a universal-style format and an 87mm stroke, but they are different product ranges.

• MACHZero: Patented high-efficiency core designed to minimise lost motion
• MACHZero: Highly flexible conduit for long or complex routes
• MACHZero: Blue abrasion-, UV- and chemical-resistant jacket
• MACHZero: Stainless-steel cable-end fittings
• C8: Standard universal 33C-style Ultraflex cable with conventional construction

Use MACHZero when its high-efficiency construction or route flexibility is required. Use the exact existing model for a straightforward replacement unless the complete control and engine connection have been rechecked.

How Do I Select the Correct Cable Length?

Use the installed cable route and the exact cable-end positions when selecting the length.

• Replacement cable: Check the model and length printed on the existing cable. Where the marking cannot be read, measure the cable from tip to tip and round up to the next whole foot.
• New inboard or sterndrive installation: Measure the unobstructed routed distance A + B from the control to the throttle or shift connection, then round up to the next whole foot.
• New outboard installation: Measure A + B, add 3ft / 90cm for engine movement, then round up to the next whole foot.
• Cable route: Follow the actual installed path rather than a straight-line measurement and allow sufficient space for smooth bends and service access.

An incorrectly short cable can restrict movement or pull against the fittings. Excessive length can create unnecessary bends and increase control effort.

Dimensions and Fitment

• Stroke: 87mm / 3.4in
• Length unit: Whole-foot cable sizes
• Listed length range: 5ft to 36ft
• Jacket colour: Blue
• Cable-end material: Stainless steel
• General routing bend guidance: Use smooth bends; verify the control and cable instructions for the installed system

The higher flexibility of the MACHZero assists with complex routing but does not permit kinking, crushing or forcing the cable around an unsuitable bend.

Construction and Design

• Patented high-performance MACH cable construction
• Core designed to maximise efficiency and minimise lost motion
• Highly flexible conduit
• High-resistance blue outer jacket
• Resistance to abrasion, UV exposure and chemicals
• Stainless-steel cable-end fittings
• 87mm / 3.4in operating stroke
• Designed for compatible marine throttle and shift systems

Control effort is also affected by cable length, bend count, control-box condition and engine-linkage load. A high-efficiency cable cannot compensate for a seized or incorrectly adjusted linkage.

Installation and Adjustment

Mechanical throttle and shift controls are safety-critical. Installation should be completed by a competent marine technician.

Before installation:

• Confirm the exact cable model and selected length
• Place the control and engine linkage in neutral or idle as applicable
• Isolate the engine starting circuit
• Inspect the control box, cable brackets, terminals and engine linkage for wear or corrosion
• Confirm the planned route provides smooth bends and clearance from heat, sharp edges and moving parts
• Identify every connection kit, clevis, pivot or clamp required at both ends

During installation:

• Route the cable with the fewest practical bends
• Do not kink, crush, twist, drill, shorten or modify the cable assembly
• Do not clamp the outer casing tightly enough to deform it
• Keep the cable clear of exhaust components, belts, steering linkages and moving machinery
• Secure the cable outer casing at the specified support points
• Adjust throttle and shift travel independently where two cables are fitted
• Use only the connection hardware specified for the control and engine

After installation, operate the control through its complete range with the engine switched off and confirm that:

• The control moves smoothly through its complete range
• Neutral and idle positions are correctly aligned
• Forward and reverse engage positively without forcing the linkage against its stops
• Full throttle can be selected without over-travelling the engine linkage
• The cable does not bind, pull tight or contact another component
• All cable terminals, clamps, pins and retainers remain secure
• Outboard engine steering and tilt movement do not stretch or kink the control cables

Do not operate the boat if the control is stiff, neutral cannot be identified positively, a cable is damaged or any terminal or retainer is loose.

Maintenance and Replacement

Inspect the complete control-cable installation regularly and before extended use.

• Check the cable jacket for cuts, abrasion, crushing, swelling or heat damage
• Inspect exposed terminals, pins, clevises and clamps for corrosion or wear
• Check that the cable remains supported without tight or distorted clamps
• Confirm that throttle and shift movement remains smooth and accurately adjusted
• Replace a cable that is kinked, seized, abnormally stiff or mechanically damaged
• Do not attempt to repair a damaged push-pull cable by straightening, splicing or welding it

Frequently Asked Questions

Is MACHZero the same as a standard C8 cable?

No. It shares the universal-style application and 87mm stroke, but MACHZero uses Ultraflex’s patented high-efficiency construction and blue jacket.

Can MACHZero be used for throttle and shift?

Yes, where the control box and engine or gearbox linkage are compatible. Many installations require one cable for throttle and a second cable for shift.

Is the control box included?

No. This listing covers one control cable in the selected length.

Can I choose the length from the straight-line distance?

No. Measure the complete routed path and include the additional allowance required for an outboard engine.

Does every Ultraflex control accept MACHZero directly?

No. Some controls require a model-specific connection kit. Check the exact control model before ordering.

Can a damaged cable be lubricated and reused?

A kinked, seized or damaged cable should be replaced rather than repaired. Follow the control manufacturer’s maintenance instructions.
